Keynote Speakers

The following speakers have accepted to give keynotes at *SEM 2019.

Title: Identifying Affective Events and the Reasons for their Polarity

Abstract: Recognizing affective states is essential for narrative text understanding and for applications such as conversational dialogue, summarization, and sarcasm recognition. Many tools have been developed to recognize explicit expressions of sentiment, but affective states can also be inferred from events. This talk will focus on "affective events", which are generally desirable or undesirable experiences that implicitly suggest an affective state for the experiencer. For example, buying a home is usually desirable and associated with a positive affective state, but being laid off is undesirable and associated with a negative state. First, we will describe a weakly supervised learning method to induce affective events from a text corpus by optimizing for semantic consistency. Second, we aim to characterize affective events based on Human Needs Categories, which often explain people's motivations, goals, and desires. We will present a co-training model for Human Needs categorization that uses an event expression classifier and an event context classifier to learn from both labeled and unlabeled texts.

Bio: Ellen Riloff is a Professor in the School of Computing at the University of Utah. Her primary research area is natural language processing, with an emphasis on information extraction, affective text analysis, semantic class induction, and bootstrapping methods that learn from unannotated texts. Prof. Riloff has served as the General Chair for the EMNLP 2018 conference, Program Co-Chair for the NAACL HLT 2012 and CoNLL 2004 conferences, on the NAACL Executive Board for 2004-2005 and 2017-2018, the Computational Linguistics Editorial Board, and the Transactions of the Association for Computational Linguistics (TACL) Editorial Board. In 2018, Prof. Riloff was named a Fellow of the Association for Computational Linguistics (ACL).

Title: Task-Independent Sentence Understanding

Abstract: This talk deals with the goal of task-independent language understanding: building machine learning models that can learn to do most of the hard work of language understanding before they see a single example of the language understanding task they're meant to solve, in service of making the best of modern NLP systems both better and more data-efficient. I'll survey the (dramatic!) progress that the NLP research community has made toward this goal in the last year. In particular, I'll dwell on GLUE—an open-ended shared task competition that measures progress toward this goal for sentence understanding tasks—and I'll preview a few recent and forthcoming analysis papers that attempt to offer a bit of perspective on this recent progress.

Bio: I have been on the faculty at NYU since 2016, when I finished my PhD with Chris Manning and Chris Potts at Stanford. At NYU, I'm a core member of the new school-level Data Science unit, which focuses on machine learning, and a co-PI of the CILVR machine learning lab. My research focuses on data, evaluation techniques, and modeling techniques for sentence understanding in natural language processing, and on applications of machine learning to scientific questions in linguistic syntax and semantics. I am an area chair for *SEM 2018, ICLR 2019, and NAACL 2019; I organized a twenty-three person team at JSALT 2018; and I earned a 2015 EMNLP Best Resource Paper Award and a 2017 Google Faculty Research Award.

Call for papers

*SEM 2019 brings together researchers interested in the semantics of natural languages and its computational modeling. The conference embraces symbolic and probabilistic approaches, and everything in between; theoretical contributions as well as practical applications are welcome. The long-term goal of *SEM is to provide a stable forum for the growing number of NLP researchers working on all aspects of semantics. Topics of interest include, but are not limited to:

  • Lexical semantics and word representations
  • Compositional semantics and sentence representations
  • Statistical, machine learning and deep learning methods in semantic tasks
  • Multilingual and cross-lingual semantics
  • Word sense disambiguation and induction
  • Semantic parsing; syntax-semantics interface
  • Frame semantics and semantic role labeling
  • Textual inference, entailment and question answering
  • Formal approaches to semantics
  • Extraction of events and causal and temporal relations
  • Entity linking; pronouns and coreference
  • Discourse, pragmatics and dialogue
  • Machine reading
  • Extra-propositional aspects of meaning
  • Multiword and idiomatic expressions
  • Metaphor, irony, and humour
  • Knowledge mining and acquisition
  • Common sense reasoning
  • Language generation
  • Semantics in NLP applications: sentiment analysis, abusive language detection, summarization, fact checking, etc.
  • Multidisciplinary research on semantics
  • Grounding and multimodal semantics
  • Human semantic processing
  • Semantic annotation, evaluation and resources
  • Ethical aspects and bias in semantic representations

Important Dates

Paper submission deadline: March 10, 2019
Notification of acceptance: April 3, 2019
Camera-ready papers due: April 10, 2019
Timezone: as long as it’s the date mentioned, anywhere on earth; UTC-12.

Submission Instructions

Submissions to *SEM 2019 must describe unpublished work and be written in English. We solicit both long and short papers.

Long papers describe original research and may consist of up to eight (8) pages of content, plus unlimited pages for references. Final versions of long papers will be given one additional page of content (up to 9 pages) so that reviewers' comments can be taken into account.

Short papers describe original focused research, project or system description, and may consist of up to four (4) pages, plus unlimited pages for references. Upon acceptance, short papers will be given five (5) content pages in the proceedings. Authors are encouraged to use this additional page to address reviewers comments in their final versions.

As the reviewing will be blind, the paper must not include the authors' names and affiliations. Furthermore, self-references that reveal the author's identity, e.g., "We previously showed (Smith, 1991) ..." must be avoided. Instead, use citations such as "Smith previously showed (Smith, 1991) ...". As for online paper sharing, at *SEM, we adopt the ACL policy for submission, which can be found here. Papers that do not conform to requirements will be rejected without review. For a paper to be included in the conference proceedings, at least one of the authors must be registered as a participant at the *SEM conference.

Submissions to *SEM should follow this year's NAACL style, as detailed here: https://naacl2019.org/calls/papers/

Please note that double submission of papers will need to be notified at submission.
